English clubs are enduring mixed fortunes in the Champions League so far this season.

Some may be feeling confident of making it through to the knockout stages, whilst others are probably a little more pesimistic.

However, if any team makes it all the way to the final, they will be subject to a big change that UEFA announced at the end of last season.

Whilst most fans focused on the news in March that kick-off times would be changing, some may have missed another announcement that came with it.

From this season, Champions League finalists will be able to name 12 subs for the game, which UEFA say will give "clubs and, in particular, coaches more flexibility regarding substitutes, and facilitate their squad management for the most important fixture of the season."

Meanwhile, in the knockout rounds as a whole, clubs will be able to make a fourth substitution if their tie goes to extra-time - something that has already become commonplace in other competitions.

If a club were to sign a player in January who has already featured in a UEFA competition this season, they will now also be able to play for their new club - which also marks a change from previous years.
